Java Double類中的常量

Double類中的常量

代碼如下所示

//Double類中的常量

public class DoubleConstant{

public static void main(String[] args) {

double maxDouble = Double.MAX_VALUE;

double minDouble = Double.MIN_VALUE;

int maxExponent = Double.MAX_EXPONENT;

int minExponent = Double.MIN_EXPONENT;

double negativeInfinity = Double.NEGATIVE_INFINITY;

double positiveInfinity = Double.POSITIVE_INFINITY;

double naN = Double.NaN;

int doubleSize = Double.SIZE;

int doubleBytes =Double.BYTES;

System.out.println("double類型最大正有限值為:"+maxDouble);

System.out.println("double類型最小正非零值為:"+minDouble);

System.out.println("double類型的二進(jìn)制補(bǔ)碼位數(shù):"+doubleSize);

System.out.println("double類型的二進(jìn)制補(bǔ)碼字節(jié)數(shù):"+doubleBytes);

}

}
